Hi. We know the "minimum" values to configure the linux kernel for MQ.

They are

kernel.msgmni = 1024
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.sem = 500 256000 250 1024
fs.file-max = 32768
net.ipv4.tcp_keepalive_time = 300

But how must we increase them if we have 4 queue managers ?
And if 8 ?

All I see is to use MQCONFIG tool

>>> http://www-01.ibm.com/support/docview.wss?uid=swg21271236

but I would like to know other opinions.

Thanks. Sebastian.
